Xpress Insight captures extra information alongside the basic contents of the entities it is managing.
This data is made available as extra dimensions to the original data. The JavaScript functions for getting and setting the data values accept a dimension parameter to indicate that the action should be performed on an extra dimension of the data.
Normal Dimension
The dimension parameter defaults to 0, which indicates the normal data dimension. The following table shows what data is captured as the normal dimension for each type of data managed by Xpress Insight.
